Functions of Two Variables Functions of two variables can be visualized in many ways: heat maps in 2D, contour curves in 2D, wireframes in 3D, surfaces in 3D. We begin by defining a function of two ...

A theory for the transient lift of two-dimensional supersonic wings given in a previous paper (Strang 1948) is extended to cover three-dimensional wings of the purely supersonic class. It is found ...
